Have you ever noticed that when it actually comes time to migrate your CAD data, you wake up one morning all alone? On one hand, it’s your data. You made it. You allowed it to grow organically into the amorphous amoeba, or set of amoebas, it has become. The structure, integrity, and complexity of the data set is a direct result of a company’s historical design process. This is always the wildcard in the time, complexity, and cost if a successful integration. Realistically, asking a PLM vendor to tell you if your data is a mess is like asking a hospital photographer if your baby is ugly. Unfortunately it is their place to point out inconsistencies, poor practices, and lapses in data discipline. These data disciplines may not have even made strategic sense until you have gone to the precipice of “implementing a system”.
